Description
Set in the richly layered world of the Fated series, The Unwritten Heir is a character-driven romantasy blending sharp banter, political intrigue, found family, and a slow-burn enemies-to-lovers romance built on tension and restraint.
Riven Augustine never meant to breach a forbidden realm.
But when she's captured by a fae court where silence is law and even memory can be erased, she learns she's been marked by powers that will stop at nothing to find her.
One careless deal. One binding law. Now Riven is trapped as the unwilling key to a fracturing realm—and the captive of a king who wields silence like a blade. His council demands her death. His realm demands her compliance. And the dangerous bond forming between them threatens everything she’s fighting to protect.
He needs her to break the curse tearing his realm apart.
All she wants is to go home.
But the prophecy binding them together demands a sacrifice—and fate has never been kind to those who try to rewrite it.
A slow-burn, forced-proximity, enemies-to-lovers romantasy perfect for readers who love powerful heroines, layered magic systems, and immersive fantasy worlds with devastating emotional payoff.
No prior reading required.
A Note From the Publisher
This is the first book in the Fated Legacies series, set within the world of my completed seven-book Fated series. While longtime readers may recognize certain names and lore threads, this story was written to stand fully on its own.
The Unwritten Heir is a slow-burn romantic fantasy driven by emotional tension, political stakes, and layered worldbuilding. The romance develops gradually, with intimacy increasing later in the story. Readers who enjoy character-focused plots, found family dynamics, and payoff that builds over time will find this especially rewarding.
Content includes fantasy violence, themes of grief, political manipulation, and explicit on-page sexual content that is emotionally driven and integral to character development.
Honest reviews are sincerely appreciated, particularly on retail platforms upon release. Thank you for taking the time to read and share your thoughts.
With gratitude,
Cosette Verga
Advance Praise
"This has the emotional depth that made me fall in love with the Fated series, but the story is completely its own. Riven is not a repeat—she has her own fire, her own struggles, and watching her journey felt fresh and authentic."
"A beautiful journey of healing and becoming unapologetically yourself—wrapped in fated bonds, touch her and die tension, and a slow burn that kept me hooked the entire time."
"The worldbuilding is immersive and easy to follow. The magic system is approachable for new readers, yet rewarding for longtime fans. The pacing allows characters to breathe while still keeping you turning pages."
"Toran brings a completely different energy, and the tension between him and Riven is incredible. The slow burn, the restraint, the emotional pull—it all builds to something so satisfying."
"I finished this in one sitting. That ending has me counting the days until book two."

Marylou J, Reviewer
I absolutely loved this book. It has that same emotional depth and immersive feel that made me fall in love with the original Fated series, but the story is completely its own.
Riven is not a repeat of Areya, and I really appreciated that. She has her own fire, her own struggles, and her own growth. Watching her journey unfold felt fresh and authentic. The same goes for Toran—he is not another Ash. He brings a completely different energy to the story, and the tension between him and Riven is incredible.
The slow burn was done so well. The buildup, the restraint, the emotional pull—it kept me hooked the entire time. I loved the tension and how it simmered throughout the book.
It was also really special to see cameos from the original Fated cast at the beginning. It felt like coming home while still stepping into something new.
I cannot wait for book two. That ending has me counting the days.
